APPARATUS FOR PILING BARS.

SPECIFICATION forming part of Letters Patent No. 581,934, dated May 4,1897.

Application filed February 1, 1897- fierial No. 621,479. (No model.)

To aZZ whom it may concern,-

Be it known that I, SIGMUND V. HUBER, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented or discovered a certain new and useful Improvement inApparatus for Piling Bars, &c. ,of which improvement the following is aspecification.

The invention described herein relates to certain improvements inmechanism for piling bars, 850., as they come from reducing-rolls orshear mechanism; and the invention has for its object a constructionwhereby the bars may be superposed one upon the other in regular orderand alinement regardless of any twisting or warping which they may havereceived; and it is a further object of the illvent-ion to provide forthe lateral shift-in g of such a pile of bars along a hotbed or othertable for subsequent treatment.

In general terms the invention consists in the construction andcombination, substantially as hereinafter more fully described andclaimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan view showing a portion of a hotbed and myimproved bar-piling mechanism applied thereto, and Fig. 2 is a sectionalelevation of the same.

In the practice of my invention the hotbed is formed by a series ofparallel rails 1, supported on suitable posts or standards 2. At one endof the hotbed is found the pilingpit, the walls of such pit being formedby plates 3, secured to suitable standards 4, the latter beingpreferably arranged a distance apart equal to the widest bar which it isdesired to treat. At suitable points along the length of the pit arearranged a series of sets of slides 5 and 6, which are mounted insuitable vertical guides and are operated independently of each other byfluid-pressure cylinders 7 and 8. The connection between the slides andtheir operating-cylinders is formed by bell-crank levers 9 and 10,having one end connected by links 11 to the slides, while the oppositeendsor arms are connected by links 12 to the piston-rods 13. As clearlyshown by reference to Fig. 2, the upper end of one of the slides of eachset is formed with an inclined edge, so that any article dropped orresting upon such slide will move toward and rest against one wall ofthe piling-pit.

At the end of the hotbed a slide 14 is arranged on suitable guideways15, said slide being provided with suitable bearings 16 for the shafts17 of feed-rollers 18, said rollers being positively driven from thepower-shaft 19 by a flexible train of gearing consisting of thegear-wheel 20 on the power-shaft, the idler 21, and gear-wheel 22 on ashaft 23, which is also provided with series of beveled pinions 24,adapted to intermesh with correspondingly-shaped pinions on the shafts17 of the feed-rollers. The shaft 23 is mounted in suitable bearingssecured on the slide or carriage 14, so as to move back and forththerewith. The journals of the idler 21 are mounted in suitable bearingsformed in the ends of links 25 and 26, which have their outer endsloosely mounted on the shafts 19 and 23, respectively. By reason of thisc011- nection from the shafts 19 and 23 to the journal of the idler 21the latter is held in constant operative relation with the gear-wheels20 and 22 regardless of the position of the slide or carriage 14.

As clearly shown in Fig. 2, the feed-rollers 1S overhang the front edgeof the slide 14, so that when the latter is in the position shown insaid figure the rollers willprojectacro ss the upper end of thepiling-pit and will support and positively feed any article placedthereon to any desired position along the pit. In orderto prevent anyarticle from passing laterally off from the rollers while being fedalong, guides 27 and 28 are arranged along opposite edges of the pit,the guides 27 being secured permanently in place, While the guides 28are secured to arms 29, which are keyed to a shaft 30, mounted insuitable bearings upon the slides 14. The shaft 30 is rotated in orderto raise the arms and the guidestrips carried thereby by means of an arm31, keyed to the shaft and having its opposite end connected to one armof the bell-crank lever 32, pivot-ally mounted on a suitable post orstandard of the slide 14, while the opposite end of said lever has aloose or slotted connection to a rod 34, passing through an abutment 33on the slide or carriage 14. The outer end of this rod 34 is connectedby a link 35 to an arm 36, which is secured to a shaft 37,

also provided with an arm 38, connected by links 39 to the piston-rod 40of the fluid-pressure cylinders 41. The rod 34 is provided at a suitablepoint along its length with heads or enlargements a and 1), adaptedafter certain preliminary movements of the rod to bear against theabutment 33 of the carriage and on its continued movement to shift thecarriage toward and from the hotbed and thereby pull the rollers 18 outof line with the piling-pit. The preliminary movement of the rod 36 willshift the arms 29 to the positions shown in full and dotted lines inFig. 2.

This bar-piling mechanism is preferably arranged in line with the lastreducing-pass of a suitable mill, so that the bar can be fed directlyonto the rollers 18 in line with the pit as they come from thereducing-rolls. As soon as the article has passed out oft-hereducing-rolls and rests entirely upon the rollers 18 the carriage 14 isdrawn back, pullin' g the rollers out of line with the pit andpermitting the bar to drop onto the inclined ends of the slides 5 in thepit. The article is prevented from moving laterally with the rollers bythe stationary guide-strip 27. As the article drops upon the inclinedend of the slides 5 it will slip along and rest against the front wallof the piling-pit. The rollers 18 are returned to normal position forthe reception of another bar, and as soon as that bar has reached thedesired position above the pit the rollers are again Withdrawn,permitting the bar to drop upon the one previously placed in position.This operation is contin ued until the desired number of bars have beenarranged upon the slides 5, which, it should be observed, are dropped adistance approximately equal to the thickness of the bars after each barhas been placed in position in the manner stated. As soon as the desirednumber of bars have been piled the slides 6, having a straight upperend, are raised, so as to straighten the pile of bars and lift them upuntil the under surface of the lowest bar is on a level with or slightlyabove the upper surface of the rails 1 of the hotbed. In order to shiftthe pile of bars onto the hotbed, a series of trucks 42 are mounted uponrails 43 parallel with the rails 1 of the hotbed, and on these trucksare pivotally mounted dogs 44, having at one end upturned toes or lugs45, which are normally held above the level of the rails 1 by weights 46on the opposite ends of the dogs, as clearly shown in Fig. 2. The trucksare moved back and forth by ropes 47, Which may be Wound upon suitablepulleys or may be made in the form of an endless belt passing aroundguide and driving pulleys, as clearly shown and describedin anapplication, Serial No. 617,177, filed by me December 28, 1806.

Then the pile of bars has been raised in the manner stated, the buggiesor trucks are shifted to the left, as shown in Fig. 2, so that the toeson the dogs will pass under and engage the rear side of the pile ofbars, whereupon the buggy is shifted to the right, pulling the pile uponthe rails 1 of the hotbed. The slides 6 are then lowered, the slide 5raised to the desired position, and the earriage 14 shifted to the rightto bring the rollers 18 in line with the piling-pit and the guidestrip28 to its operative position.

I claim herein as my invention 1. In an apparatus for piling bars,plates,

&c., the combination of a receiver arranged in the line of movement ofthe plates or bars as they come from reducing-rolls or other mechanism,a series of rollers arranged transversely of the receiver and adapted tosupport the plates or bars, and means for moving the rollers out of andinto line with the receiver, substantially as set forth. 2. In anapparatus for piling bars, plates, &e., the combination of a series ofverticallymovable slides arranged in the line of movement of the platesor bars as they come from the reducing-rolls or other mechanism, aseries of rollers arranged transversely of the path of movement of theslides, and means for moving the rollers out of and into such line ofmovement of the slides, substantially as set forth.

3. In an apparatus for piling bars, plates, &e., the combination of areceiver arranged in the line of movement of the plates or bars as theycome from the reducing-rolls or other mechanism, a series of rollersarranged transversely of the receiver, guides for preventing a lateralmovement of the plates as they move on the rollers, and means forlifting one of said guides and moving the rollers out of and into linewith the receiver, substantially as set forth.

In testimony whereof I have hereunto set my hand.
